National Corrections Reporting Program, 1986 (ICPSR 9276)

This study was conducted to provide a consistent and
comprehensive description of convicted persons' entrance into and
departure from correctional custody and correctional supervision. To
accomplish this goal, data were gathered from official state prison
records on topics such as race, sex, and age of inmates, length of
time in jail, length of time in prison, and type of offense committed.

Methodology

Sample:
All persons incarcerated in state prisons in 36 states,
the Federal Prison System, the California Youth Authority, and the
District of Columbia.

Data Source:

official prison records of prisoner population movement

Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:

Performed consistency checks.

Standardized missing values.

Performed recodes and/or calculated derived variables.

Checked for undocumented or out-of-range codes.

2006-03-30 File SP9276.ALL was removed from any previous datasets and flagged as a study-level file, so that it will accompany all downloads.

2006-01-12 All files were removed from dataset 6 and flagged as study-level files, so that they will accompany all downloads.

2006-01-12 All files were removed from dataset 5 and flagged as study-level files, so that they will accompany all downloads.

2006-01-12 All files were removed from dataset 4 and flagged as study-level files, so that they will accompany all downloads.

2006-01-12 All files were removed from dataset 4 and flagged as study-level files, so that they will accompany all downloads.

2005-11-04 On 2005-03-14 new files were added to one
or more datasets. These files included additional setup files as well
as one or more of the following: SAS program, SAS transport, SPSS portable,
and Stata system files. The metadata record was revised 2005-11-04 to
reflect these additions.

1997-08-01 The data have been checked for wild or invalid
codes, and the codebook and SAS and SPSS data definition statements
now document these codes. In addition, the codebook is now available
as a PDF file only, and the variable and value labels have been
expanded.
